DISK-HARROW snnnnn rmamen Application filed February 27; 1929.serialfna'e aoss.

This invention relates to a combined seeder and harrow, an object beingto provide a combination machine which will reduce the amount ofmachinery necessary for planting as well as for harrowing. In addition,the invention will also reduce the amount of power required foroperating an extra machine.

Another object of the invention is the provision of a machine of theabove character in which the grain dischargeboots may be adjusted withrespect to the harrow disks, together with a novel construction of bootwhich reduces liability of clogging the discharge ends of the boots. p I

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings V Figure 1 is an elevation of one section ofacombination harrow and seeder.

Figure 2 is an end view.

Figure 3 is an enlarged fragmentary sectional view taken substantiallyon the line 33 of Figure 1.

Figure 4 is a section on the line 44 of Figure 3.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the invention as shown may be made ofseparate sections mounted upon a suitable frame so that one or moresections may be used as desired. j

Each section comprises a seed hopper 10 which is connected with an axle11 by means of bearing members 12, and mounted upon this axle are disks13. i

I The hopper is provided with sultable dropping mechanism which includesa shaft 14: and this shaft is driven by means of a sprocket chain 15 andits operation is controlled by a'clutch 16. A rod 17 and an operatinglever 18 serve to provide means for moving the clutch into and out ofengagement. j The seeder mechanism. further includes a 5 bar 19 which isdisposed horizontally beneath the hopper 10. This bar is substaniftially U shaped in cross section as shown in Figure 4 of the drawingsand is provided with spaced openings 20 which receive grain dischargeboots 21. The bar 19 is provided with spaced openings 22 for the passageof bolts so that it may be bolted to the lower ends of spacedsubstantially V-shaped straps 23 which are secured to opposite sides ofthe hopper 10. r ,6)

The grain discharge boots 21 are located H adjacent the disks 19 and areadjustable with respect to these disks. For-this purpose, the bar 19carries U bolts 24; which engage the boots 21 .so as to hold them invertically and 5 rotatably adjustable position. Downward movement of theboots is limited by a flange 25 which surrounds the upper ends of theseboots. The boots 21 receive the grain from the hopper through dischargespouts 26. 19

The lower ends of the boots 21 are curved as shown at 27 and extendingupwardfrom the lower curved extremities of the bootsand opposed to thedisks 13 are discharge openings 28 through which the grain passes. .15The arrangement and position of the openings 28 prevent these openingsfrom becoming clogged due to an accumulation of dirt or other substancethrown up by the "disks.

The chain 15 is'maintained in proper op- 30 erative condition throughthe medium of a chain tightener. This tightener comprises a sprocket 29which engages the chain and which'is carried at one end of an arm 30.

The opposite end of this arm is pivotally 35- vmounted as shown at 31 toan'arm' 32 and.

these arms are connected by means of 'a spring 33 which yieldingly holdsthe sprocket 29 engaged with the chain. 7 j

The invention is susceptible v of various 3,0

changes in its form, proportions and minor details of construction andthe right is herein reserved to make-such changes as properly fallwithin the scope of the appended claims.

,Having described the invention what isieo W claimed is:

1. In a seeder attachment for disk harrows, a seed hopper, asubstantially U-shaped bar having spaced openings therein, graindelivering boots adjustably positioned within said openings, means tosecure the bar to the hopper, and spouts to direct the grain from thehopper into the boots.

2. In a seeder attachment for disk harrows, a seed hopper, asubstantially U-shaped bar having spaced openings therein, graindelivering boots adjustabiy positioned within said openings, means tosecure the bar to the hopper, spouts to direct the grain from the hopperinto the boots, said boots having V their lower ends curved andhavingopenings extending upward from their lower extremities with the openingsopposed to the disks.

In testimony whereof I affix my signature. I T I OTTO El REIMER.
